Description

Technical Field

[0001] The utility model relates to the technical field of a refrigeration water pump frequency conversion control cabinet, in particular to a refrigeration water pump frequency conversion control cabinet with an anti-impact structure. Background Art

[0002] The chilled water pump variable frequency control cabinet is a device used to control the operation of the chilled water pump. It is widely used in central air conditioning systems, industrial cooling systems and other equipment that requires temperature control. It adjusts the speed of the chilled water pump through the inverter to achieve precise control of the water flow and pressure, thereby achieving energy saving and optimizing system performance. The variable frequency control cabinet can adjust the operating status of the water pump according to actual needs, improve the efficiency of the system, and extend the service life of the equipment. In addition, the chilled water pump variable frequency control cabinet also has overload protection, short circuit protection and other safety functions to ensure the safety and stability of the system operation.

[0003] The variable frequency control cabinets for chilled water pumps currently on the market are susceptible to water spills when working in extreme environments. This is mainly because the traditional control cabinet design does not take into account waterproof protection measures under extreme weather conditions. Once the water level in the external environment rises, water can easily enter the control cabinet, causing short circuits, corrosion and damage to electrical components, seriously affecting the normal operation of the system. Existing solutions often only add a simple waterproof cover to the outside of the control cabinet, which has limited effect and cannot completely solve the problem of water damage.

[0004] Therefore, there is an urgent need for a chilled water pump variable frequency control cabinet with an anti-impact structure to solve the above technical defects. Utility Model Content

[0005] The utility model aims to provide a refrigeration water pump frequency conversion control cabinet with an anti-impact structure to solve the problem of being easily impacted by overflow water proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a refrigeration water pump variable frequency control cabinet with an anti-impact structure, comprising a cabinet body and an overflow outlet, a group of bases are arranged on both sides of the bottom end of the cabinet body, an overflow outlet is opened at the bottom end of the cabinet body between the bases, an anti-impact structure for preventing water immersion is arranged above the overflow outlet, the anti-impact structure comprises a drainage cavity, the drainage cavity is located at the bottom end of the cabinet body, a group of drainage outlets are arranged on both sides of the drainage cavity, a water level alarm is installed at the top of the drainage cavity, a water storage tank is arranged on the left side outside the cabinet body, a water pump is fixed at the front end of the water storage tank, the drainage outlets are respectively connected to drainage pipes outwardly, and the output ends of the drainage pipes are respectively connected to the water storage tanks.

[0007] Furthermore, the drainage cavity is in a bucket shape and is a component made of metal material.

[0008] Furthermore, the drain outlet is located at a position higher than the drain cavity, and the water level alarm is located at a position higher than the drain outlet.

[0009] Preferably, a first threaded rod and a second threaded rod are vertically arranged on both sides of the cabinet, the top of the first threaded rod is fixedly connected to a servo motor, the first threaded rod and the top of the servo motor are respectively fixedly sleeved with a driving gear and a driven gear, and the driving gear and the driven gear are meshingly connected.

[0010] Furthermore, threaded blocks are respectively sleeved on the outside of the first threaded rod and the second threaded rod, and one end of the threaded blocks is respectively fixedly connected to a negative pressure fan.

[0011] Furthermore, the first threaded rod and the second threaded rod are arranged in parallel and correspondingly on the left and right sides in the horizontal direction.

[0012] Furthermore, a group of limiting rods are welded on one side of each of the first threaded rod and the second threaded rod.

[0013] Preferably, heat dissipation windows are welded on both sides of the cabinet outer wall, fixing frames are respectively fixed on both sides of the cabinet inner wall, multiple groups of guide fins are arranged at equal intervals outside the fixing frames, and the guide fins extend from the heat dissipation windows to the outside of the cabinet respectively.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the refrigeration water pump frequency conversion control cabinet with an anti-impact structure not only prevents external water overflow impact, prevents flood risks caused by extreme weather such as rainstorms, realizes efficient heat dissipation, and prevents failures or damage caused by overheating, but also ensures the heat dissipation effect while maintaining a dust-free environment inside the equipment;

[0015] (1) The cabinet is provided with a raised base, a water level alarm, a water pump, a drain port, and a drain cavity. Once the external environment is flooded with a high water level, the water overflows into the drain cavity. As the water level rises to a position detectable by the water level alarm, the water level alarm sends a signal to the system to trigger the start of the water pump. The water pump is driven by an internal motor and uses the centrifugal force generated by the rotation of the impeller to pump out the water. The water is pumped away through the drain port and transported to the water storage tank to prevent the water level from rising further, thereby protecting the equipment inside the cabinet from water damage, effectively preventing the risk of floods caused by extreme weather such as heavy rains, and protecting the electrical equipment inside the cabinet.

[0016] (2) A servo motor, a driving gear, a driven gear, a first threaded rod, a second threaded rod, a threaded block, a negative pressure fan, and a heat dissipation window are provided. Two sets of threaded rods are provided on both sides of the cabinet. The servo motor drives the driving gear and the driven gear to mesh and rotate. The first threaded rod and the second threaded rod on the same side rotate in opposite directions. The threaded blocks move up and down respectively, driving the negative pressure fan on the same side to move up and down alternately. The negative pressure fan draws away the high-temperature air inside the cabinet and introduces it to the outside through the heat dissipation window, thereby achieving the purpose of efficient heat dissipation. The problem of low heat dissipation efficiency of traditional control cabinets is solved, and failure or damage caused by overheating is prevented;

[0017] (3) A negative pressure fan, guide fins, and heat dissipation windows are provided. A plurality of parallel guide fins are provided on one side of the heat dissipation negative pressure fan. The negative pressure fan is driven by a motor. The rotation of the blades inside the motor generates negative pressure, and the internal hot air is guided to the guide fins. The parallel arrangement of the guide fins can effectively enhance the heat conduction efficiency and ensure that the internal heat is quickly dissipated to the external environment. The heat dissipation window partially covers the guide fins located outside the cabinet to play a dust-proof role. At the same time, the negative pressure fan continues to work to ensure that the hot air is discharged from the heat dissipation window, so as to keep the temperature inside the cabinet within a safe range, thereby ensuring the heat dissipation effect and maintaining a dust-free environment inside the equipment.

Two sets of threaded rods are set on both sides of the cabinet 1. They are driven by a servo motor 18. The servo motor 18 accurately adjusts the rotation through an internal control system. Speed ​​and torque drive the driving gear 17 and the driven gear 19 to mesh and rotate, and the first threaded rod 13 and the second threaded rod 20 on the same side rotate in the opposite direction.
